IMPROVEMENT IN DEVICES F OR DETACHING HORSES. i

Specification forming part of Letters Patent No. 145,662, dated December16, 1873; application filcd July 14, 1873.

To all whom it may concern:

-Be it known that I, ISRAEL L. LANDIS, of Lancaster, in the county ofLancaster and in the State of Pennsylvania, have invented certain newand useful Improvements in Device for Detaching Horses from Vehicles;and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a device for detaching horses from whiffletrees, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a view of a whitfletree with my device attached thereto.Figs. 2 and 3 are sections of the same.

A represents a whiffietree, having at each end a pin, a, upon which theend of the trace is to be placed, and around each end of the whiflietreeis a ferrule, b, as shown. B represents a metal plate, provided with alongitud inal slot, 6, placed against the end of the whiffletree, thepin a projecting through the slot 6. At the rear edge of the whiflietreethe plate B is bent outward and then forward, as shown at d. The other(front) end of the plate B has an arm, f, extending inward, and theextreme end of said arm is bent toward the whiffletree. The plate B is,by

means of a spring, 0, connected with and at tached to a collar orferrule, h, placed a suit able distance from the end around thewhifflet-ree, or to an arm, h, extending inward from the ferrule b onthe rear side of the whiffletree. A cord, on, is attached to the end ofthe arm f on the plate B, and passed around a staple or roller, t, atthe end of the whiflietree, and then through a staple at the center ofthe same. When the trace is put on the pin a, the spring 0 holds theplate B in such a position that the end (1 thereof bears against the endof the pin a, and prevents the trace from slipping off. By pulling uponthe cord m, the plates B are thrown outward, the main parts of theplates pushing the traces ofi' from the pins a a. The bent end of thearm f acts as a stop against the staple or roller 6 for the outwardmovement of the plate B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The combination of thewhiffletree A, having a ferrule, 11, and pin a at each end, the platesB,with slots 0, outward-projecting bars d, and arms f, formed of onepiece and con nected to the springs O, which are attached to thewhiffletree, all constructed substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of July, 1873.
